My Plextor finally kind of kicked the bucket about 3 months ago.  It was just about 5 years old.  My burn speeds has been really slowed.  Nothing beyond a 1X when burning a DVD.  Occassionally (once every couple months, within the last year of its life), my PC would hang at the post screen.  Since the new drive I never had a problem with boots.  So I attributed it to the failing drive.
Overall the drive served me well and was pleased.  IIRC it cost me $180 back in the day.
Now I have an Asus SATA drive.  This is actually my 2nd drive, the first being DOA from Newegg.
